Damping Ratio

Damping ratio, abbreviated as \(\zeta\), a dimensionless number, describes how oscillations in a system decay after a disturbance.

 

Damping Ratio formula

\(\large{ \zeta  =  \frac{ 1 }{ 2 \; Q }    }\)

\(\large{ \zeta }\)  (Greek symbol zeta) = damping ratio	\(\large{ dimensionless }\)
\(\large{ Q }\) = quality factor	\(\large{ dimensionless }\)
